1 Claim.

This invention aims to provide, in an inexpensive form, a device adapted to be used by the wholesale milk handler, and so constructed that the milk will be cooled immediately, thereby re- 5 tarding bacterial activity, the milk being aerated to eliminate animal heat and odor or off flavor, a stirring of the milk, in order to cool it, being obviated, and the general construction being such that the article is sanitary, in that it may be taken down readily for cleaning or sterilization.

A mechanic who abides by what is claimed can make changes in the precise form shown, without departing from the spirit of the invention.

Fig. 1 is a vertical section wherein the device is assembled with a milk can;

Fig. 2 is a vertical sectional view wherein parts are enlarged from the showing of Fig. 1;

Fig. 3 is a cross section on the line 3--3 of Fig. 2;

Fig. 4 is a fragmental perspective showing a portion of the fastener or cover for the strainer.

The numeral l marks a tank, containing a cooling medium 2, such as ice water or brine, and in the cooling medium is located a milk can 3 having a reduced neck 4, extended to form a flared mouth 5 which projects upwardly above the level of the cooling medium 2.

The numeral 6 designates a balloon-shaped container, provided in its top and at one side with an inlet opening I, the container having a downwardly tapered intermediate portion 8,

merging into a cylindrical sleeve 9 there being external lugs H) on the tapered intermediate portion 8, spacing the part 8 from the mouth 5 of the milk can, and spacing the sleeve 9 from the neck 4 of the milk can, to form a passage II by which air can find an exit from the can 3, as

milk accumulates in it. The neck 9 is supplied,

near its lower end, with circumferentially spaced, small perforations l2, and when the container 6 is seated in the upper part of the milk can 3.,

the lugs l0 stop the downward movement of the milk can, and the perforations l2 are so located that they will spray the milk on the underside of the crown of the milk can 3, and downwardly upon the inner surface of the body of the can.

" The numeral 14 marks a plunger which has limited vertical movement, in the top of the container 6, since the plunger has spaced stop shoulders l5, between which the top of the container is located. Near its lower end, the plunger 55 I4 is provided with an abutment It, a holding device, such as a nut ll, being threaded on the lower end of the plunger. A valve is bound between the abutment I6 and the nut I1, and preferably embodies disks l8, between which is placed a resilient packing washer IS. The packing washer or disk l9 has a close sliding fit' in the sleeve 9 of the container 6. The vertical throw limited by the shoulders I5 is such that when the plunger I4 is depressed, the perforations l2 in the sleeve 9 will be open, but when the plunger is raised, the 10 packing disk IQ of the valve will close the perforations. A frusto-conical deflector 20 is supported on the uppermost of the disks IS, the

plunger l4 passing removably through the top of the deflector. l5

Near its upper end, the sleeve 9 of the container 6 is provided with circumferentially spaced brackets 2i, and above the brackets are located keepers 42. A strainer rests on the brackets 2|, and is made up of a perforated lower disk 22, a 20 perforated upper disk 23, and a thin strainer pad 24 between the disks, the strainer pad being made of gauze, cotton or the like. The parts last above enumerated are peripherally notched, as shown at 25 in Fig. 1, so that they can be slid 25 down on the brackets 2|, past the keepers 42.

On top of the strainer 22--24-23 is placed an upwardly dished cover or retainer 25 which, as shown in Fig. 4, has peripheral notches 21, there being upwardly inclined tongues 28 at the ends of 30 the notches. When the cover or retainer 26 is rotated, the tongues 28 guide the keepers 42 into the notches 21 and, when the cover or retainer is rotated far enough, the keepers 42 engage above the cover or retainer 26, the part 26 holding the 35 filter 22-24--23 tightly compacted.

For the convenient rotation of the cover 26, it is provided with upstanding wings 29, located on opposite sides of a central opening 30 in the cover.

By means of the plunger M, the valve is raised until the packing disk l9 covers the perforations 12 of the neck 9 of the container 6. Milk is poured into the container 6, through the inlet opening 1, until a sufficient head of milk is 45 created in the container. Then the plunger I4 is pushed downwardly, until the packing disk I9 uncovers the opening 12. The milk flows downwardly throughthe opening 30 of the cover 26, and through the strainer 22-24-23, where the suspended impurities in the milk are removed. The outwardly and downwardly inclined circumferential wall of the deflector 20 carries the milk to the perforations l2 of the sleeve 9, and a head. is created at the openings l2. The milk spurts through the perforations l2 and is sprayed on the inside of the milk can 3.

The device, although simple in structure, consummates the objects set forth in the opening part of this specification, inasmuch as the milk is strained, aerated and cooled, with no operations other than those involved in pouring the milk into the container 6 and raising or lowering the plunger It.

Having thus described the invention, What is claimed is:

In a milk handling device, a can having a top provided with a neck, a container in the neck, means for spacing the container from the neck, to form an open annular air outlet for the can and disposed about the container, the container having circumferentially-spaced perforations discharging laterally into the can in the same plane with the under surface of the top, at the place where air from the can enters the air outlocation of the perforations with respect to the 10 under surface of the top eifecting lateral dispersion of air into the milk, along the under surface of the top, and a deflector on top of the valve and having a downwardly and outwardly inclined circumferential surface leading to the per- 15 forations.
